    Superb combination of BMP280 and SI7021. On one tiny PCB is whole meteo station ready to be used in your project. I'm very happy with this purchase and I will probably buy another one in near future.

    Very compact, the temperature sensors of the two integrated chips are within 0.5 degrees Celsius of each other, so that is a relatively good indication of accuracy. You will likely need a library for each, but the readings are very steady and seem about as accurate as I can check. BE CAREFUL, RUNS ON 3.3V, THIS IS NOT MENTIONED ON THE PAGE. 5V might work but you might fry it. Plan ahead and get a board with a 3.3V pin for easy wiring.

    Includes BMP280 (temperature+pressure) and SI7021 (temperature+humidity) Everything via I2C. Both perfectly managed by Arduino library : https://github.com/orgua/iLib (i2c-sensor-lib ilib by Ingmar Splitt, available in Arduino standard libraries) More sensors, less wires than DHT22. Temp from BMP and Temp from SI are consistent. Very small physical footprint compared to DHT.

    The sensor is working fine in combination with an ESP8266 running espeasy, but Domoticz has trouble displaying the incomming data correctly. Connected to the raspberry running Domoicz itself, no problems. Conclusion: This is a great little sensor, packing three functions in a single square cm!
